Rotational position sensor with a two-part rotatable member to resist jamming

A rotational position sensor, comprising:

• a stationary member comprising a magnetically sensitive component;
• a rotatable member comprising a first portion and a second portion, said first and second portions being rotatable relative to each other, said second portion being shaped to be attachable to a rotatable shaft;
• a magnet attached to said first portion, said magnetically sensitive component being disposed within the magnetic field of said magnet, said magnet being rotatable relative to said magnetically sensitive component in response to rotation of said rotatable member;
• and
• a resilient member connected to said first and second portions resist relative rotational movement between said first and second portions and to permit said relative rotational movement between said first and second portions in response to a predetermined force urging said relative movement, said resilient member being a torsion spring.

A rotational position sensor, comprising:

• a stationary member comprising a magnetically sensitive component;
• a rotatable member comprising a first portion and a second portion, said first and second portions being rotatable relative to each other, said second portion being shaped to receive a rotatable shaft;
• a magnet attached to said first portion, said magnetically sensitive component being disposed within the magnetic field of said magnet, said magnet being rotatable relative to said magnetically sensitive component in response to rotation of said rotatable member;
• and
• a resilient member connected between said first and second portions to permit relative movement between said first and second portions only in response to a predetermined magnitude of force urging said relative movement, said rotatable member being supportable by said rotatable shaft in noncontact relation with said stationary member.
